How to join plastic ductwork? What kind of welding device to use? What materials and diameters we have in stock? Can plastic ducts & fittings be stored outside? These and more questions about chemically resistant plastic ventilation ductwork.

Industrial dust extraction is used in welding industry, metalworking industry, woodworking industry, food and pharmaceutical industry. Installation air-tightness is crucial for this type of systems, since any kind of leakage may cause dust leaking outside of the ductwork and reduce dust extraction efficiency.

Easy, quick and precise installation of ducts even in hard to reach places is the main advantage of the STRUT support system. The available selection of mounting accessories make for a fully professional fixing system.

The PWQ-R flange cleat is used for joining rectangular ducts. A channel of particular length is slid on PQ-20 or
